Application filed July 7, 1925. Serial No. 42,013.

To all whom it may concern:

Be it known that I, RICHARD A. HALEY, a citizen of the United States,residing at Hollywood, in the county of Los Angeles and State ofCalifornia, have invented certain new and useful Improvements inVVinding Apparatus, of which the following is a specification. v

My invention relates to a winding apparatus primarily adapted for use inthe laboratory in connection with the developing, washing, and drying ofmotion picture llllTlS.

One object of my invention is to producea motor-driven mechanism whereinboth hands of the operator may be free to handle the film.

Another object is to provide a construction driven by an electric motorhaving a rheos'tat in its circuit under control of a treadle switch, anda brakeapplicable bythe treadle switch as it moves to open position.

A third object is to devise the apparatus in an inexpensive, simple,compact, unitary, and portable form capable of ready attachment to asupport and to be controlledwithout undue interference with the normaluse of the support.

The more specific objects and advantages will appear from' aconsideration of the following description taken in connection with" theaccompanying drawing illustrating one operative embodiment.

In said drawing:

Fig. l is a view of'the device in side elevation as attached to afragmentarily shown table;

Fig. 2 is a view of the parts of Fig. 1 taken at a right angle thereto;and

Fig. 3 is a diagram of the electrical connections.

Referring specifically to said drawings, designates a conventionalattaching bracket or base which may be generally of U-shape as shown, sothat it may embrace the edge portion of a table T or other support andbe rigidly but removably secured thereto by set screws 11.

To an upper arm 12. of the attaching bracket 10, a winding mechanism Wis mounted, having for instance a casing 13 detachably bolted thereto at14. Mechanism W has a Winding drum 15 carried by a rotatable shaft 16adapted to be driven from a shaft 1 through intermediate gearing notshown.

'nism R for control of the motor.

Said'shaft 18 is adapted to be driven by an electric motor 19 whose baseis detach-ably bolted or otherwise fastened at 20 to a lower arm 21 ofbracket 10. To this end a bevel. gear 22 is keyed to the main shaft 23of said motor and meshes with a bevel gear 24 on a vertical countershaft25 to which a bevel gear .26 is fastened so as to mesh with a similargear 27 keyed to the shaft 18. Shaft 25 may be journaled in a bearing 28integral with bracket 10 and held therein against vertical displacementby collars 29 on said shaft.

The motor 19 is arranged under and in line with the winding mechanismand below the motor and in line with the same, and mechanism W is arheostatic switch mecha- Specifically, this mechanism has a base'plate30 adapted to be bolted; to the floor at 81. On the base plate 30- is abox or casing 32 forming the rheostat proper in that it has resistance33 therein and exterior contacts 34 therefor in proper insulatedrelation to the casing. Pivoted to the base plate 80 at 35 is aSWltCllfll'lll or treadle 36 carrying a contact 87 insulated therefromand adapted for successive engagement with contacts 34 to throw moreorless resistance into the motor circuit to govern its speed ofoperation. Arm 36 is normally maintained in and urged to the offposition by an expansive spring 38 fastened between the pedal and thebase.

The parts are shown in electrical diagram in Fig. 3 and with referencethereto, a usual plug 39 is adapted to be screwed into an electricsocket. From the plug one conductor 40 leads to motor 19. A slackconductor 41 extends from the motor 19 to contact 37. Resistance 33 isconnected to the plug 89 by a conductor 42. A switch 43 may be includedin conductor 41 to be left open when the apparatus is not operating toprevent accidental operation through depression of treadle 36.

A brake rod 44 is vertically slidable in bearing 28 and has an arcuateshoe 45 adapted for normal braking engagement against the periphery of adrum 46 integral with or attached to gear 27. The rod 44 moves with thetreadle 36-and is connected thereto by a pin 47 on the rod engaging anelongated slot 48 of the pedal. By means of this construction the arm 36is urged to off position by spring 38 and such movement of the armapplies the brake rod 44 at shoe against drum dB to arrest motion of thewinding drum 15. Said winding drum 15 preferably comprises a disk 48 anda hub lug or stub shaft 49.

The various conductors cannot be identified in Figs. 1 and 2 since theyare conveniently grouped in insulation 50.

Presuming operation, plug 39 is attached to an appropriate socket suchas an electric lamp socket and the operator places one foot on thetreadle 36. lVit-h the electric current otherwise established,depression of treadle 36 engages the contact 37 with uppermost contact34, thus starting the motor 19 at the slowest speed. Further depressioncauses contact 37 to successively engage the remaining contacts 3a todecrease the amount of resistance in circuit and thereby increase thespeed of operation of the motor. As a result of the structure both handsof the operator are left free to control the material being wound.

Said motor 19 drives shaft 23, and the latter by means of gears 22 and2% drives countershaft 25. Shaft 25, through gears 26 and 27, drivesshaft 18, gearing l7, shaft 16 and drum 15. The material is wound aroundthe stub shaft l9. To cease operation, the pressure of the foot ontreadle 36 is released and spring 38 throws said treadle to the OEposition of Fig. 1, thus breaking the circuit to the motor 19. At thesame time, treadle 36 applies the brake rod eta against drum 46 andarrests motion of the winding drum 15.

The apparatus is particularly useful in the laboratory in connectionwith motion picture films, before they are placed on reels, andparticularly in connection with their development, washing and dryingand formation into rolls. As one foot controls the motor and brake, bothhands may engage thc film. At the same time, it is to be realized thatthe compact and relatively attentuated arrangement of the elementsavoids parts which hamper the operator or normal use of the table.

Various changes may be resorted to within the spirit and scope of myinvention.

I claim:

1. A winding apparatus comprising a winding mechanism, an electric motorbelow the same, an attaching bracket for said mechanism and motor, atrcadle switch for and below the motor, a driving connection from saidmotor to said mechanism and supported on said bracket, a drum forming apart of said connection, and a brake rod movable with said treadleswitch disposed relatively close to said connection and engageable withsaid drum.

2. A winding apparatus comprising a winding mechanism, vand electricmotor substantially in line therewith below the same, an attachingbracket between and by which said mechanism and motor are carried, abearing on said bracket, an upstanding countershaft journaled in saidbearing, gearing to drive said countershaft from said motor, gearing todrive said mechanism from said countershaft including a drum, a basebelow the motor, a rheostat on said base, a switch arm pivoted to saidbase and coacting with the rheostat to control the motor circuit, aspring on said base urging the switch arm to off position, and a brakeguided by said attaching bracket and connected to said switch arm forapplication against the drum through off movement of the switch arm.
